Alt Text: What Is It & How To Write It

In this guide, you will learn about alternative text (alt text): what it is, why it is important for SEO, how to use it correctly, and more!

This is a very practical and to-the-point guide that contains tips and advice you can immediately use to improve your website’s image SEO and accessibility.

What Is Alt Text?

Alt text (or alternative text), also known as the alt attribute or the alt tag (which is not technically correct because it is not a tag), is simply a piece of text that describes the image in the HTML code.

What Are The Uses Of Alt Text?

The first function of alt text was simply to describe an image that could not be loaded.

Many years ago, when the internet was much slower, alt text would help you know the content of an image that was too heavy to be loaded in your browser.

Today, images rarely fail to load, but if they do, then it is the alt text that you will see in place of an image.

Now, alt text has also started to play a role for both search engine bots and people using screen readers:

  • Alt text helps people with disabilities (for example, using screen readers) learn about the image’s content.
  • Alt text also helps search engine bots understand the image’s content and context.

Of course, like every element of SEO, it is often misused or, in some cases, even abused.

Let’s now take a closer look at why alt text is important.

Why Alt Text Is Important

The web and websites are a very visual experience. It is hard to find a website without images or graphic elements.

That’s why alt text is very important.

Alt text helps translate the image’s content into words – thus making the image accessible to a wider audience, including people with disabilities and search engine bots that are not clever enough yet to fully understand every image, its context, and its meaning.

Why Alt Text Is Important For SEO

Alt text is an important element of on-page SEO optimization.

Proper alt text optimization makes your website stand a better chance of ranking in Google image search.

Yes, alt text is a ranking factor for Google image search.

Depending on your website’s niche and specificity, Google image search traffic may play a huge role in your website’s overall success.

For example, in the case of ecommerce websites, users very often start their search for products with a Google image search instead of typing the product name into the standard Google search.

Google and other search engines may display fewer product images (or not display them at all) if you fail to take care of their alt text optimization.

Without proper image optimization, you may lose a lot of potential traffic and customers.

Why Alt Text Is Important For Accessibility

Visibility in Google image search is very important, but there is an even more important consideration: accessibility.

Fortunately, in recent years, more focus and emphasis has been put on accessibility (i.e., making the web accessible to everyone, including people with disabilities or/and using screen readers).

Suppose alt text of your images actually describes their content instead of – for example – stuffing keywords. In that case, you are helping people who cannot see this image to better understand it and the content of the entire web page.

Let’s say one of your web pages is an SEO audit guide that contains screenshots from various crawling tools.

Would it not be better to describe the content of each screenshot instead of placing the same alt text of “SEO audit” into every image?

Let’s take a look at a few examples.

Alt Text Examples

Finding many good and bad examples of alt text is not difficult. Let me show you a few, sticking to the above example with an SEO audit guide.

Good Alt Text Examples

So, our example SEO guide contains screenshots from tools, such as Google Search Console and Screaming Frog.

Some good examples of alt text may include:

<img src=”google-search-console-coverage-report.jpg” alt=”The Coverage Report in Google Search Console showing the number of indexed and excluded pages”>
<img src=”google-search-console.jpg” alt=”Google Search Console tool from Google”>
<img src=”screaming-frog-html-pages.jpg” alt=”List of HTML pages in Screaming Frog”>
<img src=”screaming-frog” alt=”Screaming Frog crawl in progress”>

Tip: It is also a good idea to take care of the name of your file. Using descriptive file names is not a ranking factor, but I recommend this as a good SEO practice.

Bad And/Or Spammy Alt Text Examples

I’ve also seen many examples of bad alt text use, including keyword stuffing or spamming.

Here is how you can turn the above good examples into bad examples:

<img src=”google-search-console-coverage-report.jpg”alt=”seo audit free, seo audit cheap, seo audit specialist, seo audit, seo audits”>
<img src=”google-search-console.jpg” alt=”google seo ,seo google, google, seo, google search console seo”>
<img src=”screaming-frog-html-pages.jpg” alt=”seo auditor, seo audit, seo audits”>
<img src=”screaming-frog” alt=”seo audit”>

As you can see, the above examples do not really provide any information on what these images actually show.

You can also find examples and even more image SEO tips on Google Search Central.

Common Alt Text Mistakes

Stuffing keywords in the alt text is not the only mistake you can make.

Here are a few examples of common alt text mistakes:

  • Failure to use the alt text or using empty alt text.
  • Using the same alt text for different images.
  • Using very general alt text that does not actually describe the image. For example, using the alt text of “dog” on the photo of a dog instead of describing the dog in more detail, its color, what it is doing, what breed it is, etc.
  • Automatically using the name of the file as the alt text – which may lead to very unfriendly alt text, such as “googleseachconsole” or “google-search-console” or “photo2323,” depending on the name of the file.

Alt Text Writing Tips

And finally, here are the tips on how to write correct alt text so that it actually fulfills its purpose:

  • Do not stuff keywords into the alt text. It won’t help your web page rank for these stuffed keywords.
  • Describe the image in detail, but still keep it relatively short. Avoid adding multiple sentences into the alt text.
  • Use your target keywords, but in a natural way, as part of the image’s description. If your target keyword does not fit into the image’s description, don’t use it.
  • Don’t use text on images. All text should be added in the form of HTML code.
  • Don’t write “this is an image of.” Google and users know that this is an image. Just describe its content.
  • Make sure you can visualize the image’s content by just reading its alt text. That is the best exercise to make sure your alt text is OK.

How To Check If A Page Uses The Alt Text

Now you know all the best practices and common mistakes of alt text. But how do you actually check what’s in the alt text of the images of a website?

You can analyze the alt text in the following ways:

Inspecting an element (right-click and select Inspect when hovering over an image) is a good way to check if a given image has alt text.

However, if you want to check that in bulk, I recommend one of the below two methods.

Install Web Developer Chrome extension.

Next, open the page whose images you want to audit.

Click on Web Developer and navigate to Images > Display Alt Attributes. This way, you can see the content of the alt text of all images on a given web page.

To check the alt text of the images of the entire website, use a crawler like Screaming Frog or Sitebulb.

Crawl the site, navigate to the image report, and review the alt text of all website images.

How to Block ChatGPT From Using Your Website Content

Published

How to Block ChatGPT From Using Your Website Content

There is concern about the lack of an easy way to opt out of having one’s content used to train large language models (LLMs) like ChatGPT. There is a way to do it, but it’s neither straightforward nor guaranteed to work.

How AIs Learn From Your Content

Large Language Models (LLMs) are trained on data that originates from multiple sources. Many of these datasets are open source and are freely used for training AIs.

Some of the sources used are:

  • Wikipedia
  • Government court records
  • Books
  • Emails
  • Crawled websites

There are actually portals and websites offering datasets that are giving away vast amounts of information.

One of the portals is hosted by Amazon, offering thousands of datasets at the Registry of Open Data on AWS.

Screenshot from Amazon, January 2023

The Amazon portal with thousands of datasets is just one portal out of many others that contain more datasets.

Wikipedia lists 28 portals for downloading datasets, including the Google Dataset and the Hugging Face portals for finding thousands of datasets.

Datasets of Web Content

OpenWebText

A popular dataset of web content is called OpenWebText. OpenWebText consists of URLs found on Reddit posts that had at least three upvotes.

The idea is that these URLs are trustworthy and will contain quality content. I couldn’t find information about a user agent for their crawler, maybe it’s just identified as Python, I’m not sure.

Nevertheless, we do know that if your site is linked from Reddit with at least three upvotes then there’s a good chance that your site is in the OpenWebText dataset.

More information about OpenWebText is here.

Common Crawl

One of the most commonly used datasets for Internet content is offered by a non-profit organization called Common Crawl.

Common Crawl data comes from a bot that crawls the entire Internet.

The data is downloaded by organizations wishing to use the data and then cleaned of spammy sites, etc.

The name of the Common Crawl bot is, CCBot.

CCBot obeys the robots.txt protocol so it is possible to block Common Crawl with Robots.txt and prevent your website data from making it into another dataset.

However, if your site has already been crawled then it’s likely already included in multiple datasets.

Nevertheless, by blocking Common Crawl it’s possible to opt out your website content from being included in new datasets sourced from newer Common Crawl data.

The CCBot User-Agent string is:

CCBot/2.0

Add the following to your robots.txt file to block the Common Crawl bot:

User-agent: CCBot
Disallow: /

An additional way to confirm if a CCBot user agent is legit is that it crawls from Amazon AWS IP addresses.

CCBot also obeys the nofollow robots meta tag directives.

Use this in your robots meta tag:

<meta name="robots" content="nofollow">

Blocking AI From Using Your Content

Search engines allow websites to opt out of being crawled. Common Crawl also allows opting out. But there is currently no way to remove one’s website content from existing datasets.

Furthermore, research scientists don’t seem to offer website publishers a way to opt out of being crawled.

The article, Is ChatGPT Use Of Web Content Fair? explores the topic of whether it’s even ethical to use website data without permission or a way to opt out.

Many publishers may appreciate it if in the near future, they are given more say on how their content is used, especially by AI products like ChatGPT.

Whether that will happen is unknown at this time.

Google’s Mueller Criticizes Negative SEO & Link Disavow Companies

Published

Google's Mueller Criticizes Negative SEO & Link Disavow Companies

John Mueller recently made strong statements against SEO companies that provide negative SEO and other agencies that provide link disavow services outside of the tool’s intended purpose, saying that they are “cashing in” on clients who don’t know better.

While many frequently say that Mueller and other Googlers are ambiguous, even on the topic of link disavows.

The fact however is that Mueller and other Googlers have consistently recommended against using the link disavow tool.

This may be the first time Mueller actually portrayed SEOs who liberally recommend link disavows in a negative light.

What Led to John Mueller’s Rebuke

The context of Mueller’s comments about negative SEO and link disavow companies started with a tweet by Ryan Jones (@RyanJones)

Ryan tweeted that he was shocked at how many SEOs regularly offer disavowing links.

He tweeted:

“I’m still shocked at how many seos regularly disavow links. Why? Unless you spammed them or have a manual action you’re probably doing more harm than good.”

The reason why Ryan is shocked is because Google has consistently recommended the tool for disavowing paid/spammy links that the sites (or their SEOs) are responsible for.

And yet, here we are, eleven years later, and SEOs are still misusing the tool for removing other kinds of tools.

Here’s the background information about that.

Link Disavow Tool

In the mid 2000’s there was a thriving open market for paid links prior to the Penguin Update in April 2012. The commerce in paid links was staggering.

I knew of one publisher with around fifty websites who received a $30,000 check every month for hosting paid links on his site.

Even though I advised my clients against it, some of them still purchased links because they saw everyone else was buying them and getting away with it.

The Penguin Update caused the link selling boom collapsed.

Thousands of websites lost rankings.

SEOs and affected websites strained under the burden of having to contact all the sites from which they purchased paid links to ask to have them removed.

So some in the SEO community asked Google for a more convenient way to disavow the links.

Months went by and after resisting the requests, Google relented and released a disavow tool.

Google cautioned from the very beginning to only use the tool for disavowing links that the site publishers (or their SEOs) are responsible for.

The first paragraph of Google’s October 2012 announcement of the link disavow tool leaves no doubt on when to use the tool:

“Today we’re introducing a tool that enables you to disavow links to your site.

If you’ve been notified of a manual spam action based on ‘unnatural links’ pointing to your site, this tool can help you address the issue.

If you haven’t gotten this notification, this tool generally isn’t something you need to worry about.”

The message couldn’t be clearer.

But at some point in time, link disavowing became a service applied to random and “spammy looking” links, which is not what the tool is for.

Link Disavow Takes Months To Work

There are many anecdotes about link disavows that helped sites regain rankings.

They aren’t lying, I know credible and honest people who have made this claim.

But here’s the thing, John Mueller has confirmed that the link disavow process takes months to work its way through Google’s algorithm.

Sometimes things happen that are not related, no correlation. It just looks that way.

John shared how long it takes for a link disavow to work in a Webmaster Hangout:

“With regards to this particular case, where you’re saying you submitted a disavow file and then the ranking dropped or the visibility dropped, especially a few days later, I would assume that that is not related.

So in particular with the disavow file, what happens is we take that file into account when we reprocess the links kind of pointing to your website.

And this is a process that happens incrementally over a period of time where I would expect it would have an effect over the course of… I don’t know… maybe three, four, five, six months …kind of step by step going in that direction.

So if you’re saying that you saw an effect within a couple of days and it was a really strong effect then I would assume that this effect is completely unrelated to the disavow file. …it sounds like you still haven’t figured out what might be causing this.”

John Mueller: Negative SEO and Link Disavow Companies are Making Stuff Up

Context is important to understand what was said.

So here’s the context for John Mueller’s remark.

An SEO responded to Ryan’s tweet about being shocked at how many SEOs regularly disavow links.

The person responding to Ryan tweeted that disavowing links was still important, that agencies provide negative SEO services to take down websites and that link disavow is a way to combat the negative links.

The SEO (SEOGuruJaipur) tweeted:

“Google still gives penalties for backlinks (for example, 14 Dec update, so disavowing links is still important.”

SEOGuruJaipur next began tweeting about negative SEO companies.

Negative SEO companies are those that will build spammy links to a client’s competitor in order to make the competitor’s rankings drop.

SEOGuruJaipur tweeted:

“There are so many agencies that provide services to down competitors; they create backlinks for competitors such as comments, bookmarking, directory, and article submission on low quality sites.”

SEOGuruJaipur continued discussing negative SEO link builders, saying that only high trust sites are immune to the negative SEO links.

He tweeted:

“Agencies know what kind of links hurt the website because they have been doing this for a long time.

It’s only hard to down for very trusted sites. Even some agencies provide a money back guarantee as well.

They will provide you examples as well with proper insights.”

John Mueller tweeted his response to the above tweets:

“That’s all made up & irrelevant.

These agencies (both those creating, and those disavowing) are just making stuff up, and cashing in from those who don’t know better.”

Then someone else joined the discussion:

Mueller tweeted a response:

“Don’t waste your time on it; do things that build up your site instead.”

Unambiguous Statement on Negative SEO and Link Disavow Services

A statement by John Mueller (or anyone) can appear to conflict with prior statements when taken out of context.

That’s why I not only placed his statements into their original context but also the history going back eleven years that is a part of that discussion.

It’s clear that John Mueller feels that those selling negative SEO services and those providing disavow services outside of the intended use are “making stuff up” and “cashing in” on clients who might not “know better.”

Source Code Leak Shows New Ranking Factors to Consider

Source Code Leak Shows New Ranking Factors to Consider

January 25, 2023, the day that Yandex—Russia’s search engine—was hacked. 

Its complete source code was leaked online. And, it might not be the first time we’ve seen hacking happen in this industry, but it is one of the most intriguing, groundbreaking events in years.

But Yandex isn’t Google, so why should we care? Here’s why we do: these two search engines are very similar in how they process technical elements of a website, and this leak just showed us the 1,922 ranking factors Yandex uses in its algorithm. 

Simply put, this information is something that we can use to our advantage to get more traffic from Google.

Yandex vs Google

As I said, a lot of these ranking factors are possibly quite similar to the signals that Google uses for search.

Yandex’s algorithm shows a RankBrain analog: MatrixNext. It also seems that they are using PageRank (almost the same way as Google does), and a lot of their text algorithms are the same. Interestingly, there are also a lot of ex-Googlers working in Yandex. 

So, reviewing these factors and understanding how they play into search rankings and traffic will provide some very useful insights into how search engines like Google work. No doubt, this new trove of information will greatly influence the SEO market in the months to come. 

That said, Yandex isn’t Google. The chances of Google having the exact same list of ranking factors is low — and Google may not even give that signal the same amount of weight that Yandex does. 

Still, it’s information that potentially will be useful for driving traffic, so make sure to take a look at them here (before it’s scrubbed from the internet forever).

An early analysis of ranking factors

Many of their ranking factors are as expected. These include:

  • Many link-related factors (e.g., age, relevancy, etc.).
  • Content relevance, age, and freshness.
  • Host reliability
  • End-user behavior signals.

Some sites also get preference (such as Wikipedia). FI_VISITS_FROM_WIKI even shows that sites that are referenced by Wikipedia get plus points. 

These are all things that we already know.

But something interesting: there were several factors that I and other SEOs found unusual, such as PageRank being the 17th highest weighted factor in Yandex, and the 19th highest weighted factor being query-document relevance (in other words, how close they match thematically). There’s also karma for likely spam hosts, based on Whois information.

Other interesting factors are the average domain ranking across queries, percent of organic traffic, and the number of unique visitors.

You can also use this Yandex Search Ranking Factor Explorer, created by Rob Ousbey, to search through the various ranking factors.

The possible negative ranking factors:

Here’s my thoughts on Yandex’s factors that I found interesting: 

FI_ADV: -0.2509284637 — this factor means having tons of adverts scattered around your page and buying PPC can affect rankings. 

FI_DATER_AGE: -0.2074373667 — this one evaluates content age, and whether your article is more than 10 years old, or if there’s no determinable date. Date metadata is important. 

FI_COMM_LINKS_SEO_HOSTS: -0.1809636391 — this can be a negative factor if you have too much commercial anchor text, particularly if the proportion of such links goes above 50%. Pay attention to anchor text distribution. I’ve written a guide on how to effectively use anchor texts if you need some help on this. 

FI_RANK_ARTROZ — outdated, poorly written text will bring your rankings down. Go through your site and give your content a refresh. FI_WORD_COUNT also shows that the number of words matter, so avoid having low-content pages.

FI_URL_HAS_NO_DIGITS, FI_NUM_SLASHES, FI_FULL_URL_FRACTION — urls shouldn’t have digits, too many slashes (too much hierarchy), and of course contain your targeted keyword.

FI_NUM_LINKS_FROM_MP — always interlink your main pages (such as your homepage or landing pages) to any other important content you want to rank. Otherwise, it can hurt your content.

FI_HOPS — reduce the crawl depth for any pages that matter to you. No important pages should be more than a few clicks away from your homepage. I recommend keeping it to two clicks, at most. 

FI_IS_UNREACHABLE — likewise, avoid making any important page an orphan page. If it’s unreachable from your homepage, it’s as good as dead in the eyes of the search engine.

The possible positive ranking factors:

FI_IS_COM: +0.2762504972 — .com domains get a boost in rankings.

FI_YABAR_HOST_VISITORS — the more traffic you get, the more ranking power your site has. The strategy of targeting smaller, easier keywords first to build up an audience before targeting harder keywords can help you build traffic.

FI_BEAST_HOST_MEAN_POS — the average position of the host for keywords affects your overall ranking. This factor and the previous one clearly show that being smart with your keyword and content planning matters. If you need help with that, check out these 5 ways to build a solid SEO strategy.

FI_YABAR_HOST_SEARCH_TRAFFIC — this might look bad but shows that having other traffic sources (such as social media, direct search, and PPC) is good for your site. Yandex uses this to determine if a real site is being run, not just some spammy SEO project.

This one includes a whole host of CTR-related factors. 

CTR ranking factors from Yandex

It’s clear that having searchable and interesting titles that drive users to check your content out is something that positively affects your rankings.

Google is rewarding sites that help end a user’s search journey (as we know from the latest mobile search updates and even the Helpful Content update). Do what you can to answer the query early on in your article. The factor “FI_VISITORS_RETURN_MONTH_SHARE“ also shows that it helps to encourage users to return to your site for more information on the topics they’re interested in. Email marketing is a handy tool here.

FI_GOOD_RATIO and FI_MANY_BAD — the percentage of “good” and “bad” backlinks on your site. Getting your backlinks from high-quality websites with traffic is important for your rankings. The factor FI_LINK_AGE also shows that adding a link-building strategy to your SEO as early as possible can help with your rankings.

FI_SOCIAL_URL_IS_VERIFIED — that little blue check has actual benefits now. Links from verified accounts have more weight.

Key Takeaway

Yandex and Google, being so similar to each other in theory, means that this data leak is something we must pay attention to. 

Several of these factors may already be common knowledge amongst SEOs, but having them confirmed by another search engine enforces how important they are for your strategy.

These initial findings, and understanding what it might mean for your website, can help you identify what to improve, what to scrap, and what to focus on when it comes to your SEO strategy.
